EVACUATE HOSES

The purpose of this operation is to remove the unused fuel from the hose reels. To do this the basic

pumping operation is used except the V6 (Fuel/Defuel Valve) is put in the defuel position. This routes fuel

flow to the ED (Eductor) instead of through the flowmeter. Flow through the ED (Eductor) draws the fuel

from the hose reels and then both flow back to the tank through valve V9 (Check Valve).

NOTE
